perineal body

(redirected from Central tendinous point)

cen·tral ten·don of per·i·ne·um

the fibromuscular mass between the anal canal and the urogenital diaphragm in the median plane onto which several perineal muscles insert (bulbospongiosus, external anal sphincter, superficial, and deep transverse perineal muscles); midline episiotomies extend into this structure.

perineal body

Etymology: Gk, perineos, perineum; AS, bodig
a mass of tissue composed of muscle and fascia between the vagina and rectum in females and between the scrotum and rectum in males.

perineal body

A pyramidal fibromuscular mass which is intimately linked to the integrity of the pubic floor, especially in females, the rupture of which during vaginal delivery predisposes women to uterine, rectal and bladder prolapse. It is located at the midline of the perineum, at the junction between the urogenital triangle and the anal triangle.


pertaining to the perineum.

perineal body
central tendon of the perineum. The fibromuscular mass in the median plane of the perineum where the bulbospongiosus and external anal sphincter muscles, and the levator ani and transverse perineal muscles attach.
perineal fistula
see perianal fistula.
Gelpi perineal retractor
a small self-retaining tissue retractor.
perineal hernia
a defect in the pelvic diaphragm that permits deviation of the rectum and protrusion of pelvic fat and abdominal contents, particularly the prostate and urinary bladder. Clinical signs include a uni- or bilateral ventrolateral perianal swelling with constipation or straining. Seen most often in middle-aged, male dogs, but occurs rarely in females and in cats.
perineal laceration
laceration of the perineal area such as by the birth of a foal. Three degrees of severity are recognized. First degree laceration is when only the mucosa of the vulva and vagina are involved. Second degree is when the submucosa and muscularis layers of the vulva, the anal sphincter and the perineal body are involved. Third degree is when there is also tearing through the rectovaginal septum, the muscles of the vagina and rectum, and the perineal body.
perineal reconstruction
various surgical techniques are used to repair perineal lacerations. It is necessary to reconstruct the rectal floor and vaginal roof.
perineal reflex
stimulation of the perineum causes contraction of the anal sphincter and flexion of the tail. It is a test of the integrity of the caudal spinal segments and the pudendal nerve. Called also the anal reflex.
perineal sling
a surgical technique that uses a fascial strip under the urethra to increase resistance to urine flow in the treatment of urinary incontinence.
